Present design effort of shielding for a high-current 50-MeV proton linear accelerator requires the accurate description of the neutron sources produced from proton spills at all energies of copper accelerator fixtures and from 50-MeV proton spills on aluminum beam tubes and carbon beam stops. The recent thick-target neutron spectra measurements for 30- and 52-MeV protons on carbon, iron, copper, and lead by Nakamura et al. provide part of the required source information. The remainder of the neutron source description has been obtained from theoretical calculations. Cross sections and associated neutron spectra for Al(p,xn) an Cu(p,xn) reactions from threshold to 50 MeV have been calculated at 5-MeV increments with the GNASH preequilibrium statistical nuclear model code.
